No hablo de todos vosotros: yo sé los que he elegido: mas para que se cumpla la Escritura: El que come pan conmigo|strong="G3326, G1700", levantó contra mí su calcañar.
Não digo de todos; bem sei eu aos que tenho escolhido; mas para que se cumpra a Escritura, que diz : O que come comigo, levantou contra mim seu calcanhar.
Ce n’ est pas de vous tous que je parle; je connais ceux que j’ ai choisis. Mais il faut que l’ Écriture s’ accomplisse:
Nicht sage ich von euch allen; ich weiß, welche ich erwählt habe. Aber es muß die Schrift erfüllt werden: “Der mein Brot isset, der tritt mich mit Füßen.”
Ik zeg niet van u allen: Ik weet, welke Ik uitverkoren heb; maar dit geschiedt, opdat de Schrift vervuld worde: Die met Mij het brood eet, heeft tegen Mij zijn verzenen opgeheven.
Io non parlo di voi tutti; io so quelli che ho scelti; ma, perché sia adempita la Scrittura, colui che mangia il mio pane, ha levato contro di me il suo calcagno.
Nie o wszystkichci was mówię, jać wiem, którem obrał; ale żeby się wypełniło Pismo: Który je ze mną chleb, podniósł przeciwko mnie piętę swoję.
Не о всех вас говорю; Я знаю, которых избрал. Но да сбудется Писание: ядущий со Мною хлеб поднял на Меня пяту свою.
我這話不 是指著 你們 眾人 說的，我 知道 我所揀選 的是誰。 現在要應驗 經上的話，說：『同我 吃 飯 的人用 腳 踢 我。』
I am not talking of you all: I have knowledge of my true disciples, but things are as they are, so that the Writings may come true, The foot of him who takes bread with me is lifted up against me.

Scholars' Consensus
Commentators agree that Jesus here draws a line between the eleven true disciples and Judas. He is not speaking to all of them when he pronounces the blessing of verse 17. As Barnes notes, Jesus' statement “I know whom I have chosen” distinguishes Judas from the others in terms of heart, not just office. Vincent points out that the aorist tense of “I chose” (ἐξελεξάμην) refers to the original selection of the Twelve, but the meaning here extends to God's saving purpose. Calvin insists that the perseverance of the faithful is grounded in election, not human strength. The quotation from Psalm 41:9 is taken freely from the Hebrew (Vincent notes it does not follow the Septuagint). Cambridge Bible observes that the omission of “in whom I trusted” from the citation shows that Jesus, unlike David, was never deceived about Judas. All the sources agree that the fulfillment of Scripture does not compel Judas to sin; it simply confirms that what happened was foreknown and woven into God’s plan. As Barnes puts it, “these things have occurred in order that the prophecies may receive their completion,” not that Judas was forced.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Calvinist/Reformed: Interprets 'chosen' as election to salvation. Judas was not chosen for salvation (Calvin, Gill), thus his betrayal reveals he was never truly among the elect.
- Arminian/Wesleyan: Interprets 'chosen' as appointment to apostleship (Wesley, Clarke). Judas was chosen for the office but fell through his own free will; God's foreknowledge does not determine his sin.
- Catholic/Patristic: Emphasizes divine foreknowledge without compulsion (Augustine). Judas freely chose evil, and God integrated that evil into his plan of redemption.
What is clear: Jesus foreknew Judas's betrayal, identified it as fulfilling Scripture (Psalm 41:9), and used the event to strengthen the faith of the other disciples (v.19).
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'chosen' (election vs. office) | All traditions agree Jesus chose Judas as an apostle and that Judas was among the Twelve. | Reformed traditions typically see 'chosen' as referring to election to salvation, so Judas was not elect. Other traditions (Wesleyan, Catholic) see it as appointment to apostolic office or to a specific purpose, leaving Judas's salvation as a matter of his free response. |
| Scripture fulfillment and determinism | All agree that Psalm 41:9 finds its fulfillment in Judas, and that this fulfillment demonstrates God's foreknowledge. | Some argue that this implies a divine decree that Judas would sin (Calvin); others maintain that fulfillment is a confirmation after the fact, not a cause (Barnes, Arminian/Catholic views). |
| Severity of Judas's sin | All traditions treat Judas's act as one of the most serious sins because it involved direct treachery against the Son of God in the context of intimate fellowship. | There is debate about whether Judas was predestined to this state or whether he could have repented. Catholic tradition allows for the possibility of Judas's repentance, while Reformed tradition sees his damnation as certain. |
| Use of Psalm 41:9 | All agree that Jesus applies this psalm to himself and that it teaches that the righteous suffer from those they trusted. | Some hold that David was the primary speaker and Jesus the antitype; others see a double reference where David's experience foreshadows Christ's but does not exhaust the prophecy. |
Historical & Cultural Context
John places this verse in the middle of the Last Supper, after Jesus has washed the disciples' feet (John 13:1, 17). That act of humble service makes the coming betrayal even starker. In the ancient Near East, sharing a meal was a sign of deep trust and friendship. To eat someone’s bread was to accept their hospitality and protection. For Judas to lift up his heel, a metaphor for kicking or tripping (Vincent compares it to a wrestler trying to throw his opponent), was a shocking violation of that bond. The phrase comes from Psalm 41:9, where David laments the treachery of a close friend, widely understood in Jewish tradition as Ahithophel, who advised David’s son Absalom in rebellion (2 Samuel 15, 17). Jesus applies this psalm to himself, casting Judas as a new Ahithophel and himself as the righteous sufferer. The original context of the psalm includes David’s confidence in God’s deliverance, which reinforces Jesus’ calm foreknowledge. The meal was likely a Passover seder, which heightened the symbolism: the bread of affliction became the sign of betrayal. Jesus' citation of the psalm also reminds his followers that suffering betrayal is not outside God’s story, it has been written beforehand.
Textual Notes
Reception History
Preaching This Verse
Three-point outline
- Jesus knows his own. The “I” in “I know whom I have chosen” is emphatic in Greek. Jesus is not surprised by Judas. This certainty gives comfort to believers: their standing with him rests on his choice, not their performance.
- Betrayal does not thwart God’s plan. The betrayal is framed as the fulfillment of Scripture. Evil actions do not derail God’s purposes; they are woven into a larger tapestry that ends in resurrection.
- Intimacy magnifies the wound. The detail that Judas ate bread with Jesus underlines the depth of the betrayal. It warns against presumption: proximity to Jesus, even apostleship, does not guarantee loyalty of heart.
Five-point outline
- Divine sovereignty and human responsibility. Jesus chose Judas (John 6:70), yet Judas acts freely. The verse holds both truths without flattening either.
- The depth of betrayal. Eating bread together symbolized the closest bond. Judas’s sin is not just theft or conspiracy; it is a breach of sacred friendship.
- The fulfillment of Scripture. Jesus reads his life through the psalms. The Old Testament is not a collection of proof texts but a living word that gives shape to God’s redemptive work.
- The unraveling of the plot. Jesus tells the disciples beforehand so that when it happens, they “may believe that I am he” (v.19). Foreknowledge strengthens faith, not fear.
- Comfort for the faithful. The eleven are not suspect. Jesus assures them that his words are not about all of them. The community of disciples is still secure.
Illustration hooks
- Team betrayal. A star athlete who turns against the coach who recruited and trained him, the private knowledge of weakness, the public kick.
- Trusted employee. An assistant embezzles from a small business after years of being treated like family. The owner knew something was off but still gave chances, not as a trap, but as love.
- Communion reflection. In many traditions, the bread of the Eucharist echoes this verse. Worshipers might ask: do I eat his bread and then live as if I never knew him?
Questions your congregation is asking
- If God already knows we will fail, does our effort matter?
- How do I trust after being betrayed by someone close to me?
- Does this verse mean that Judas was destined to be lost from the start?
Leading a Discussion
This verse sits right after Jesus promises blessing to those who know and do his will. Then he pulls the curtain back: one of the twelve does not share that blessing. The group is forced to sit with the reality that closeness to Jesus does not guarantee faithfulness. Invite your group to explore that tension together.
Discussion questions
- What does Jesus mean when he says “I know whom I have chosen”? How does that differ from what he said in John 6:70?
- Why does Jesus quote a psalm about David’s betrayer? What does that connection tell us about how Jesus understood his own life?
- What does the metaphor “lifted up his heel” communicate about Judas’s intention? How does it compare to other betrayal passages (e.g., Matthew 26:23)?
- How does the fulfillment of Scripture here affect the way we think about God’s control over evil actions? Does it make Judas less responsible, or more?
- Why does Jesus tell the disciples about the betrayal before it happens (v.19)? What effect does that have on them, and on us?
- If you had been at that table, how would you have reacted to Jesus’ words? Would you have felt secure or uneasy?
- How does this passage help us pray for relationships in our own church community, especially where there may be hidden conflict?

What the Commentators Say
11 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke stresses that Jesus chose Judas with full knowledge of what he would become, not to make him wicked but foreseeing his betrayal. The prophecy from Psalm 41 about a close companion turning enemy is fulfilled in Judas, whom Clarke compares to a horse that kicks the very hand that feeds it.
Barnes' Notes on the Bible Protestant 1832
Barnes draws a careful distinction between two meanings of "chosen" in this passage. Judas was chosen to the office of apostleship but not to purity of heart and salvation. The prophecy from the Psalms was fulfilled not by divine compulsion but because the same pattern of ingratitude occurred, with "lifted up his heel" picturing a runner tripping an opponent.
Calvin's Commentaries Reformed 1564
Calvin stresses that perseverance in faith does not come from human strength but from God's unchangeable election. He credits election with both the start of piety and the ability to continue in it. This divine choice alone separates the true disciples from those who, like Judas, fall away.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator points to deliberate changes in John's Greek quotation of Psalm 41:9 that link Judas to the Eucharist. The rare verb for eating, used elsewhere of consuming Christ's flesh, and the shift from "my bread" to "bread with me" both suggest Judas received the sacrament. This makes his betrayal a violation of sacred hospitality far beyond ordinary treachery.
Geneva Bible Notes Reformed 1599
The Geneva annotators emphasize that Jesus draws a sharp distinction among the disciples: he knows which ones he has chosen, and Judas is not among them. The betrayal is neither a surprise nor a failure, but the precise fulfillment of what Scripture foretold.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that when Jesus says "I know whom I have chosen," he refers to election to eternal salvation, not to apostleship, since Judas was chosen as an apostle but not to grace. He also argues that Psalm 41:9 is a direct prophecy of Judas, not Ahithophel, and David's experience was only a type of Christ.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB stresses that Judas was never truly chosen in the higher sense; he was added to the Twelve solely to fulfill his predicted destiny. The shared bread, signifying the closest family intimacy, becomes a terrible warning for all unworthy communicants who partake of Christ's Supper.
Lange's Commentary Reformed 1857
Lange sees the foot-washing as a love-feast that brings the crisis to a head. Jesus' act is not merely a lesson in humility but a decisive expression of love that purifies the faithful circle and forces the separation of the betrayer, moving events toward the cross.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry points out that though Christ had often told the
Vincent's Word Studies Evangelical 1887
Vincent notes that the Greek verb for "I have chosen" is aorist tense, meaning "I chose," and specifies it refers to selection as an apostle, not election to salvation. He then examines the word for "eateth," which originally meant to gnaw or crunch like an animal, but in John's Gospel it has lost that primitive sense when applied to Christ's flesh. The term "heel" appears only here in the New Testament and refers to a kick, not a wrestling trip.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley observes that when Jesus pronounces blessing on His disciples, He deliberately excludes one of them. Jesus knows that the very man He has chosen will betray Him, and this betrayal will fulfill the ancient prophecy.
